Catalytic Reductive Dehydration of Tertiary Amides to Enamines under Hydrosilylation Conditions
摘要:
Tertiary amides are efficiently reduced to their corresponding enamines under hydrosilylation conditions, using a transition-metal-free catalytic protocol based on t-BuOK (5 mol %) and (MeO)(3)SiH or (EtO)(3)SiH as the reducing agent. The enamines were formed with high selectivity in good-to-excellent yields.
